Two-in-one mattress with air mattress and memory foam for patient care

Abstract

A mattress, bed, cushion, or other device to support a user in a pre-determined posture. The mattress, bed, cushion, or other device includes compressible cells configured to inflate based on characteristics of particular contact areas of the user, and contact, in response to inflating based on the characteristics, the user in various contact areas to support the pre-determined posture. In particular, inflating the compressible cells based on characteristics of particular contact areas reduces the risk of the user developing pressure ulcers.
